rpmlist csh alias
Formated search of the rpm database for installed package

   alias rpmlist \

Use local yum to install
This lets yum find and install any extra dependancies the rpm may need
automatically.

    yum localinstall /path/to/package-1.0.0-1.i386.rpm

Dependancies (requires and is required by)

       rpm -q --requires xyzzy

       rpm -q --whatprovides xyzzy
       rpm -q --redhatprovides xyzzy

RPM from SRPM sources

Build a RPM directly from a source RPM
   rpmbuild --rebuild  {package}.src.rpm
Then install
   rpm -ihv /usr/src/redhat/RPMS/i386/{package}.i386.rpm

NOTE: yum can NOT download SRPM packages at this time.

Build step by step
  package=???

  # get sources
  rpm -ihv $package-*.src.rpm
  yum-builddep $package

  # %files -- check all prerequesite files are avaiable
  rpmbuild -bl /usr/src/redhat/SPECS/$package.spec

  # %prep -- extract / apply all patches -- in /usr/src/redhat/BUILD
  rpmbuild -bp /usr/src/redhat/SPECS/$package.spec

  # %build -- compile the binaries patched (above and manually) sources
  rpmbuild --short-circuit -bc /usr/src/redhat/SPECS/$package.spec

  # %install -- install the just built binaries
  rpmbuild --short-circuit -bi /usr/src/redhat/SPECS/$package.spec

  # Unpack and build the appropriate RPM's from installed package
  rpmbuild -bb /usr/src/redhat/SPECS/$package.spec

  # Rebuild SRPM source package (after changes to patching or sources tar)
  rpmbuild -bs /usr/src/redhat/SPECS/$package.spec

Clean out the whole source area

  rm -rf /usr/src/redhat/RPMS/*/* \
         /usr/src/redhat/{SRPMS,SOURCES,SPECS,BUILD}/* \
         /var/tmp/rpm-tmp.*
  chown -R anthony.anthony /usr/src/redhat

Unpackage RPM without installing...

   mkdir t
   cd t
   rpm2cpio .../RPM.rpm | cpio -idmv

-------------------------------------------------------------------------------

  rpm -tb xxx-x.x.x.tar.gz
